title: Structure and behaviour of the free radicals generated in gamma irradiated amino acid and iminodiacetic acid derivatives.
abstract: An EPR study has been carried out to investigate the structure and behaviour of the free radical formed γ-irradiated l-alaninamide hydrochloride, dl-glutamic acid monohydrate and N-(2-carboxyethyl) iminodiacetic acid powders at room temperature. The observed paramagnetic species have been attributed to the CH(3)ĊHCONH(2), HOOCCH(2)CH(2)ĊHCOOH and HOOCCH(2)CH(2)NĊHCH(2)(COOH)(2) radicals, respectively. Some spectroscopic properties and suggestions concerning possible structure of the radicals were also discussed in this study.
